In seedless plants, a fertilized egg will develop into a sporophyte. The sporophyte releases haploid spores. Seedless plants include ferns, club mosses and horsetails. They are seedless because they do not produce seeds and are instead dispersed like bryophytes.
Answer:
single-cell creatures that scientists believe were instrumental in the development of evolution
small sea crustaceans from the order of macroplankton of about 20-200 millimeters that are visible with the naked eye
Answer:
in zoology, the scientific name of a subspecies is termed a trinomen and comprises three words, namely the binomen followed by the name of the subspecies. hope this helped :0
Answer:
DNA replication is the biological process of producing two identical replicas of DNA from one orginal DNA molecule.
DNA replication occurs when the DNA strands unzip and the orginal strands of DNA serve as a template for new nucleotides to join and form a new strand. In needs to occur because existing cells divide to produce new cells.
Answer:
c. Less oxygen consumption per second
Explanation:
- The sarcomere is a functional unit of muscle tissue. During repeated muscle contractions, the oxygen delivery to the muscle is reduced.
- As noted in the question, the rate and load of muscle contractions are the same under both conditions but the differences in the number of contractions in the second day experiment only increase.
- So as the number of contractions increases, more time is required to work. But continuous work can lead to a shortage of oxygen. Therefore, due to low availability, less oxygen per second is consumed. Lactic acid production by anaerobic respiration through muscle tissue causes muscle fatigue.
- Considering other dubious options, there is no increase in load and there is not much power generation. At the same time, ATP consumption increases due to continuous contraction, so the cellular ATP / ADP ratio is generally reduced.
- Since the calcium release by the sarcomere is reduced during continuous muscle contraction and the contraction rate does not change, the cross-bridge cycling speed is not affected.
